Issue
AVUE 5304, AVUE 5354, AVUE 5305 or AVUE 5355 Light Duty Actuator does not respond to changes in control signal.
Environment
AVUE 5304 or AVUE 5354 Light Duty Actuator installed on VZX or MZX Valve Body..
AVUE 5305 or AVUE 5355 Light Duty Actuator installed on Satchwell VEU, MEU or FEU Unit Valve Body..
Cause
AVUE 5304, AVUE 5354, AVUE 5305 or AVUE 5355 Light Duty Actuator may not respond to changes in control signal due to self stroking / auto stroking procedure failing to occur when originally installed, or due to manual override having been undertaken without subsequent reset procedure having been applied.
Resolution
1. Check that 0v of 0-10v dc control signal and 0v of 24v ac power supply originate from same source.
2. Undertake Manual Override Reset.
The Manual Override Reset Button is located on the underside of the AVUE Actuator.
The purpose of the Manual Override Reset Button is to cause the Actuator to self reference.
A reset is required only in the following circumstances.
A. If the Manual Override Access screw on the top of the Actuator has been operated when the Actuator is powered up.
B. If it is necessary to re-align the Actuator to a point of self reference during periods of system maintenance.
N.B.
The AVUE is designed to reset automatically on restoration of power following a power failure.
It should be noted that it will take approximately 85 seconds (AVUE 5305 and AVUE 5355) or 110 seconds (AVUE 5304 and AVUE 5354) for the self reference procedure to be completed.
